Additional Clearance. Sometimes certain wheel, tire and brake combinations may require just a little extra clearance to prevent caliper, inner tire or dust cap rubbing. A quick and easy way to solve these problems is with a set of 5/16" (8mm) wheel spacers from AmericanMuscle.

Durable Construction. These wheel spacers are made from light weight die-cast aluminum for durability and strength, these wheel spacers are designed to last a lifetime.

Application. This set of two 5/16 inch wheel spacers are designed for use with 5 lug 5 x 4.5" wheels.

Technical Note. Longer wheel studs may be required depending on style of wheels and year/model of Mustang.

Will these be wide enough? I recently put on 10.5" tires on the rear of my 97 and the tire has about 2mm's of space between this and the shock. I just wanted to push the tire out a tiny bit just so I don't run the risk of it rubbing on my tire. Also will these work with my wheel studs? Or will the studs become too short?

The 5/16" spacer is equivalent to 7.93mm and they will begin to push the wheel off of the hub ring, and could cause vibrations when driving. Additionally, the stock wheel studs may be too short for the wheel to be fastened with the lug nuts, and we would recommend extended and reinforced studs. If you perhaps could get away with a smaller spacer, such as a 3/16" (5mm), this will not require long wheel studs for sure.

Will this fit my 2015 Mustang GT (performance package) without needing longer studs or anything? I'd like to be able to buy, install, and enjoy!
Please let me know :)
*if anyone has any pics of these in their 2015 mustang please share!*

will these spacers require longer wheel studs with a set of american muscle after market bullt whheels and a set of caliper covers

I have a 03 Mach 1 with older AFS Mach1 style wheels.They used to come 9" Rear 8 Front. I was wondering if its safe to install 5/16 spacers in front also. Also by counting turns on lug nuts when installing wheels im doing 4 1/2 turns...is this enough or should i need longer studs.??

The Wheel & Brake Spacers are safe to use front or rear wheels as long as proper lug nut thread engagement is still present. With a Mustangs 1/2"x20 Lug nuts, we typically like to see 8 turns of the lug nut from initial install to final torque of 100 Ft Lbs. With only 4.5 turns, we would recommend looking in to a longer stud, especially if spacers are planned.

I put these on the front rims at the same time I installed new rims and tires. There was vibration at speeds over 45 and pretty bad on the freeway. At first I wasn't sure if it was the spacer or the balancing of the rims, but as soon as I took the spacers off the vibration went away. I would go hub centric spacers next time over these.

it will destroy your stock bolts eventually if you don't use extended bolts because it makes lug nuts bit on less thread of each bolt so the force on less thread and they will wear out soon. i had them on for few hours. and unbearable vibration noise. total waste of money and time

Pretty straight forward product. My only small complaint is that they do not fit snugly, meaning that they move around a little bit on the hubs. Because of this, you will want to be sure to tap them with your fingers to center them once you put the wheel back on and before you tighten the lug nuts. Other than that, no issues. It was just enough to eliminate the goofy tucking on my front wheels and stop my tires from rubbing on my struts.

Great product, easy to install. Just the right amount of clearance for my new rear brakes. Pushed the rear wheels out just beyond the lip of the wheel opening for an aggressive stance. No new studs needed. Remove wheels, install, put wheels on and use. That easy. Used on my 04 GT. As always, fast shipping plus a friendly and knowledgeable staff!!!!

My 06 GT with AM 19" Chrome Offset Bullitt Deep Dish wheels required the spacer in order for the back rims to clear the caliper covers. The 19x8.5" rims in the front DID NOT require the spacer but the 19x10" in the back certainly did. Simple product that provides a simple fix...be advised it will move the tire further to the outside of the wheel well increasing debris that is picked up and thrown against the rear fender. Worth it.

I bought this product to get sufficent clearance for my caliper covers with the bullitt replacement wheels I had recently purchased and found that they left insufficent space on the wheel studs to properly secure the lug nuts. I eventually went with Eibach 13/16 inch spacers with pre-installed studs that take the rear wheels with the 18x10 inch rims just a tad beyond the wheel well.

The spacers work pretty well. They give the perfect amount of spacing and bring your tires right even with the fender well lip. The only difficult part was getting them aligned perfectly on the hub. It takes a little tricky work to get them aligned. I didn't have to change out wheel studs as there appeared to be enough threads left.

I got my first Mustang when I was 16, a two tone 91 GT red and silver with a sunroof that did not leak. And needless to say I was a bit timid to do work on it, I had not modified any vehicle before outside of installing a CD player. I got working with a friend that had a 95 GT at the time and star...
